Looking for info on SP Revelation speakers


Just picked these up. A little dinged but sound excellent. There’s not much info online and i was hoping you fine folks could shed some light on some details. There is a link attached to some pictures. Thank you in advance

Thank you for the information. I cant wait to get them back up and running and hear it for myself.
You can contact the owner and designer for the former SP Tech through here.  If you get the outboard crossover from the other member Bob should be able to help you get yours back to like they should be.
